Boiler Water Control Valve Selection

Hubbell Model BW indirect fired water heaters are factory furnished with a boiler water control system to regulate the flow of boiler water through the heating coil. The following is an overview of the various Boiler Water Control Systems available.

Modulating 3-Way Diverting ValveModulating 3-Way Diverting Valve

This is the most commonly selected method for regulating the boiler water. A 3-Way control valve allows only the required amount of boiler water into the heating coil in order to satisfy the demand. Any excess boiler water is diverted back to the boiler water circulating loop. This valve type can be selected as either electric or pneumatic powered.

Modulating 2-Way ValveModulating 2-Way Valve

This control system will allow only the required amount of boiler water into the coil to satisfy the demand. As the water temperature in the tank approaches the set point, the flow of boiler water to the coil is decreased. This control valve does not divert unused boiler water back to the circulation loop. This valve can be selected as either electric or pneumatic powered. For proper valve sizing, the boiler water pressure must be know to ensure that the valve can properly close off during operation.

Pump On/Off ControlPump On/Off Control

This control system operates via a thermostat which opens or closes the control circuit to an independent boiler water circulation pump. The thermostat is wired into the control circuit of the circulation pump and will close the control circuit when heat is required (thereby turning the pump on) and will open the control circuit when the water temperature in the storage vessel reaches the thermostat set point, thereby turning the pump off.

Model BW Specific Questions

What is the delivery time?

In most cases the delivery time for a Hubbell water heater is approximately 10 weeks after release for production, but can be 16 weeks or more depending upon the particular requirements of your application. However, there are various sizes and configurations which Hubbell has in stock for “Quick Ship” (as early as next day t to 2 weeks) to accommodate situations that require shorter delivery. Please consult with your Hubbell Sales Engineer to discuss delivery times for your application.

How does my water heater ship?

All Hubbell storage type water heaters ship via common carrier and are classified by the Commodity Classification Standards Board under National Motor Freight Classification (NMFC) class 100. Each water heater is palletized and wood crated. All Hubbell tankless water heaters, when transported using common carrier, ship class 77.5. To provide the lowest transportation cost, in most cases the shipment is made on Hubbell’s account and the freight cost is added to the invoice, commonly referred to as “Pre pay and add”. For very large shipments, the most economical method (LTL or Dedicated Truck) for transporting the water heaters to the final destination will be analyzed by Hubbell's transportation department.

Which is better for me, a tankless or storage type water heater?

It depends. A tankless water heater is sometimes referred to as a Point-of-Use (POU) or instantaneous water heater. Due to the relative small physical size of a tankless water heater compared to a storage tank water heater, a tankless option can be advantageous from a space saving perspective and can sometimes be installed closer to where you want hot water (hence the term POU). However, tankless heaters are not suited for many applications, so it is critical that before choosing to go tankless you have carefully considered all of the factors that sometimes make the tankless option more complicated and risky compared to a storage type water heater. In particular, you should understand the operational characteristics, maintenance requirements, reparability, and sometimes significant installation requirements of a tankless water heater before making a decision. Tankless units do not store heated water like a storage type water heater; they only heat water as there is demand and therefore must be sized to meet the maximum flow for the application. In some cases a tankless water heater may improve operating efficiency, but possibly at the expense of user comfort. Hubbell tankless water heaters are available in Electric Tankless or Gas Tankless

What hi-limit control is provided for an over-temperature condition?

Hubbell provides a solenoid safety system for over-temperature situations. An aquastat senses the over-temperature condition and trips a solenoid which shunts the steam supply to the water heater. For semi-instantaneous water heaters (STX and BWX models) Hubbell provides an additional solenoid (aptly named a double solenoid) system to shunt the steam from entering the heating coil and to dump over heated water in the vessel to drain. For storage water heaters (ST and BW models) Hubbell provides a single solenoid system to shunt the steam supply to the heating coil thus preventing further over heating. A storage tank water heater does not typically include a second soeloid to dump the over heated water to drain due to the large volume of water that would need to be drained which could potentially exceed the capacity of the local drain.

What temperature should I set my water heater?

For typical domestic potable hot water service the temperature of your water heater at 125°F is sufficient. This prevents wasted energy (which means cost savings for you) and also decreases the possibility of scalding water burns. If you run out of hot water on this setting, increase the temperature by five degrees incrementally until your hot water needs are met. The goal is to have the temperature set just high enough to meet your needs but within safe operating parameters. Please note that a water heater in and of itself should not be relied upon as the ultimate temperature controlling source for the hot water delivered to your fixtures. Please consult local and state codes for installation of the proper and code approved (ASSE 1016, 1070, 1017) mixing devices to achieve the safe delivery of hot water to the fixtures. For a more complete information please download the whitepaper PDF titled "Understanding Potential Water Heater Scald Hazards" developed by ASSE at the following link ASSE Whitepaper

What should I know about Legionella disease?

Legionella is the bacteria responsible for Legionnaire’s Disease, an acute bacterial infection of the lower respiratory tract. This bacterium was first identified in 1977 by the Centers for Disease Control as the cause of an outbreak of pneumonia that caused 34 deaths at a 1976 American Legion Convention in Philadelphia. Pontiac Fever is a less severe, non-pneumonia, flu-like disease that is associated with and likely caused by Legionella bacteria. Legionella is a fairly common water bacterium and has been found to exist widely in many surface water sources including lakes, rivers, streams and ponds. It can also be found in ground water sources and some soils. At the levels found in these naturally occurring sources it typically does not pose a threat to public health. When the bacterium enters a domestic water system it can find an ideal host environment of warm water temperatures (105-115°F), stagnant water areas (isolated storage tanks and dead-end piping legs) and ample food sources (sediment, scale, deposits and biofilm). Under these conditions Legionella can rapidly colonize, forming higher concentrations that can pose the public health threat of Legionnaire’s Disease. There are many methods of controlling colonization of Legionella bacteria. However, a widely accepted and preferred method is to maintain the hot water system storage temperature continually at or above 140°F. Unfortunately, the elevated temperature necessary to minimize the growth of and kill Legionella bacteria has the potential to cause serious thermal shock and scalding injuries. As such, many plumbing engineers will specify that the water heater be set to maintain water temperatures at 140°F or higher to reduce the risk of Legionella, but then specify the appropriate mixing valve to ensure safe delivery of hot water to the fixtures. For a more thorough discussion of Legionella please go to here and the following link to the US Department of Labor OSHA information regarding Legionnaires’ Disease OSHA here
